Who are Sudan's protest leaders and what are their demands?

Who are the leaders of the protest movement which is now four months old, and what are their demands.

After toppling veteran Sudanese leader Omar al-Bashir and forcing his successor, General Awad Ibn Ouf, to step down, protesters have turned their wrath against the ruling military council.

Who are the leaders of the protest movement which is now four months old, and what are their demands.

Here is a recap:

Who are the protest leaders?

The group that initially launched the protests against Bashir's three-decade rule is the Sudanese Professionals Association (SPA) made up of unions of engineers, doctors and teachers.

The anti-Bashir campaign swiftly spread across the country through cities, towns and villages, with members of all sections of the Sudanese society joining it.

The main leaders of SPA are Mohamed Yousef Ahmed Mustafa, a professor at Khartoum University, and Mohamed Naji, a doctor who had been detained soon after the protests erupted.

Teacher Ahmed al-Rabia is also a key member of SPA and so is Omar Salah, a doctor.

Weeks into the campaign, several political parties and civil society groups joined the SPA to form an umbrella group called the Alliance for Freedom and Change.

This umbrella group includes Sudan's main opposition party, the National Umma Party, and include other parties such as the Sudanese Congress Party and the Sudanese Communist Party.

Rebel groups from Darfur, South Kordofan and Blue Nile, who for years have fought government forces in the three regions are also part of the umbrella group.

What are they demanding?

The protest leaders have announced plans to unveil on Sunday a civilian body to take over from the ruling military council that took power after Bashir was ousted on April 11.

In addition to dissolving the military council, they have other demands:

- A civilian council should form a transitional civilian government to govern for a four-year term, followed by elections.

- The dissolution of Bashir's National Congress Party, with its top leaders, brought to justice -- including the ousted president.

- The confiscation of NCP properties.

- The reinstatement of the country's 2005 constitution, which the military council suspended shortly after ousting Bashir.

- The liberation of all civilians detained in connection with the protest movement, as well as army and police personnel held for refusing to open fire at protesters.

- An end to the state of emergency Bashir imposed on February 22.

- What the military rulers have done so far? -

- Lifted night-time curfew

- Detained Bashir and some other regime leaders, although the whereabouts of many senior regime figures are unknown.

- Sacked the prosecutor general as demanded by protesters.

- Accepted the resignation of Salah Ghosh, head of the country's feared National Intelligence and Security Service (NISS) who oversaw a crackdown on protesters that killed dozens, wounded hundreds and jailed thousands.
